plot.sme: Visualisation of smoothing-splines mixed-effects models
Description
A visualisation of the smoothing-splines mixed-effects model fit is obtained. For
type="model", a scatter plot of the observations overlaid with the fitted mean and
(optionally) individual curves. Confidence limits for the mean curve can optionally also be shown.
See plot.sme.model for further details. For type="raw", a trellis plot of the raw
data for each subject, with the fitted individual curves optionally overlaid. See
plot.sme.raw for further details. For type="diagnostic", a diagnostic plot of the
model residuals. See plot.sme.diagnostic for further details.
Usage
# S3 method for sme
plot(x,type="model",...)
Arguments
x
an object inheriting from class sme, representing a fitted smoothing-splines
mixed-effects model
type
the type of plot desired, currently either "model" for visualising the model
fit, "raw" for visualising the raw data or "diagnostic" for visualising the model
residuals
...
further arguments to plotSmeModel, plotSmeRaw or
plotSmeDiagnostic
Value
Depending on type, either a plot of the fitted model, a plot of the raw data or a
diagnostic plot of the model residuals
